About Wiring
Solar panel wiring
When using solar panels to charge the battery, Solar panels with a
maximum input voltage of 18V need to be connected in series. The wiring
method is as follows
Battery connection
Calculation method for battery selection
Since the inverter needs a relatively large working current when working at
full load, if the capacity of the battery is insufficient and the maximum
output current is insufficient, it will cause the battery to be deeply
discharged in a short time and cause damage to the battery.Therefore, the
scientific and reasonable choice of the battery is to increase the inverter
And battery life guarantee
Solar panels with a maximum input voltage of 36V. When multiple solar
panels are needed, please connect them in parallel
Calculation formula for battery model selection
UPS uninterruptible power supply function
Choose a suitable battery
Since the inverter requires a relatively large working current when
working at full load, if the capacity of the battery is insufficient and the
maximum output current is insufficient, the battery will be deeply
discharged for a short time and cause damage to the battery
Therefore, the scientific and reasonable selection of batteries is a
guarantee to improve the service life of inverters and batteries
Maximum battery discharge current =
inverter rated power / (battery voltage * 0.85)
Battery capacity (C) =
maximum discharge current (I) * continuous working time (H)
For example:
the maximum load is 500W,
need to continue to use for 2 hours,
the calculation method is as follows:
maximum discharge current = 500/(24*0.85)=147A;
battery capacity (C)=147*2=294AH,
so you can choose six 100AH battery,
3 batteries in parallel and then in series
The UPS includes a 120W AC charger, which can charge the battery
when there is AC input
UPS includes a function for automatic switching between battery power
supply and mains power supply
Optional AC priority power supply mode or battery priority power supply
mode
Electric power first mode: when the mains power is available, the mains
power is given priority to the load.When the mains power is abnormal, it
will automatically switch to photovoltaic power supply. Power supply to
the load (in this mode, the AC charger starts and will continue to charge
the battery)
Battery power first mode: When the battery has power, priority is given to
the load from the battery to the load.When the battery power is
insufficient, it automatically switches to mains power supply.When the
battery power is restored, it automatically switches to battery power
supply (AC charger is prohibited in this mode, (No longer charge the
battery)
Installation and operation steps

TIP: After you use the button to
switch the "PV priority" or "Utility
priority" mode again, please
restart the inverter to ensure that
the mode takes effect
Electrical cable connection
It is necessary to confirm that the inverter switch is in a safe
disconnection state, and the equipment is properly placed before
connecting the cables. Do not reverse the battery's positive and
negative poles, this may cause damage to the inverter The inverter
electrical cables must be connected in the following order:
1.Turn off the inverter switch
2.Connect the battery terminal to the battery positive and negative
terminals: the battery positive terminal is connected to the battery
positive terminal, and the battery negative terminal is connected to the
battery negative terminal Make sure the battery terminals and cable
terminals are in good contact, otherwise it is easy to cause cable
heating
3.Turn on the inverter switch, start the inverter
4.Connect the load to the AC output socket on the output side panel of
the inverter
Note that the car cigarette lighter is only allowed to output 150 watts of
power, and exceeding the power may affect the safety of use
Recommended environment
The installation and use environment of the inverter should be well
ventilated, away from water sources, heat sources, and flammable and
explosive materials.Avoid installing the inverter in an environment with
direct sunlight, dust, volatile gases, corrosive substances, and excessive
salt
Note
The operating temperature range of the inverter is -10 ~ 40. If you want to
use it in an environment of more than 40, please use the standard of
derating 10% for every more than 1. The best temperature for battery
operation is 20 ~ 30. 30 working in an environment will reduce the battery
life, and working in an environment with a temperature below 20 will
shorten the battery backup time
The front and rear panels of the inverter should be at least 60mm away
from the wall or adjacent equipment
Avoid any objects covering the ventilation holes of the front and rear
panels of the inverter, so as not to hinder the ventilation and heat
dissipation of the inverter, causing the internal temperature of the machine
to rise and affecting the service life
Matters needing attention
1.The AC output of this machine is strictly prohibited to be connected in
parallel or connected to the power grid in any way, otherwise it will burn the
equipment
2.To ensure safe and normal use, the load power should be gradually
increased, and the total power of the electrical appliances must not
exceed the rated power of the machine
3.When using inductive loads, please select 2 to 3 times the load power
4.Vacuum pump motors should be turned off before starting because the
instantaneous starting current is too large. It is strictly forbidden to start
frequently
Warning
5. The machine should be placed indoors. In a well-ventilated place, the
device should not be covered by other objects, and there should be no
flammable or explosive products nearby
6. It is strictly forbidden to connect to the input end of the device
